My wife and her bull’s game of domination and free use [wife perspective]

I have a cuck dynamic with my wife, and she recently came into a fetish with her regular bull that turns me on a lot.

They set up a game where, at any time of the day, if he calls her using a pre-agreed code on messenger, she has to drop everything she’s doing to go to him solely to give him a really sloppy blowjob, with him finishing in her mouth and her swallowing if he orders it. After that, she comes back home. No conversation, no foreplay, no affection, no him satisfying her or anything. Like she’s a sex toy.

They’ve done this about three times already. Once in his car, another in his office, another at his house. She tells me that what excites her about the fetish is being controlled, dominated, and focusing solely on his pleasure—that what gives her the most pleasure is having total focus on his pleasure. In fact, what she likes most is when he finishes in her mouth because he really enjoys that (and she’s even came herself in that situation).
